A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 136 N at an angle of 27.0° above the horizontal. The box has a mass of 21.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (a) Find the acceleration of the box. m/s2 (b) The student now starts moving the box up a 10.0° incline, keeping her 136 N force directed at 27.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box? m/s2, up the incline

![**Problem Statement:**
A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 136 N at an angle of 27.0° above the horizontal. The box has a mass of 21.0 kg, and the coefficient of kinetic friction between the box and floor is 0.300.
(a) Find the acceleration of the box.
\[ \text{Acceleration:} \, \, \_\_\_\_\_\_\_\_ \, \text{m/s}^2 \]
(b) The student now starts moving the box up a 10.0° incline, keeping her 136 N force directed at 27.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?
\[ \text{Acceleration:} \, \, \_\_\_\_\_\_\_\_ \, \text{m/s}^2, \, \text{up the incline} \]
